I was hoping you guys could give me some suggestions on a radiator that will fit into the Corsair Obsidian 800D Case on the Roof where the 3 fan mounts are. I wan't to know what radiator is the best to cool a Core i7 Overclocked to 4.0GHz and possibly a GTX 3** Series card when they come out. Also Because I am Australian I don't have the privilege of being able to buy from NCIX and the only Online Water Cooling store that will ship to Australia that I know of is DangerDens so I can only get ones from there. I don't know which one to get.

If you are limited to Danger Den's store, I'd go with the GTX360. However, Performance-Pcs.com advertises worldwide shipment, and they stock everything. Or our Canadian source dazmode.com just gave me an estimate for AUS, and he carries Feser rads.
